1/2" Brass Swing Check Valve

This inline swing check valve uses a brass body and brass seat to stop reverse flow in residential plumbing systems. It connects via 1/2" FNPT threads on both ends and opens at a cracking pressure of 0.725 psi. The unit handles water up to 200 psi at 73°F and steam up to 120 psi WSP. It is designed for horizontal mounting only.

Replaces worn or missing backflow preventers

Swap this valve in when an existing check valve leaks, chatters or no longer seals against reverse flow. The jump is worth it if the old unit cannot hold 200 psi water pressure or 120 psi steam pressure at the rated temperatures. It also suits new installations that need a simple gravity-operated swing mechanism with a 10 gpm flow rating.

Verify pipe size, orientation and temperature limits

Confirm the line uses 1/2" FNPT fittings and that the valve can be installed horizontally. Check that operating temperatures stay between 32°F and 212°F and that system pressure does not exceed 200 psi for water or 120 psi for steam. This product contains chemicals listed under California Proposition 65.

Questions about this item

What thread size and connection type does this 1/2" swing check valve require for installation?

It uses FNPT x FNPT connections on a 1/2 inch pipe size, so both ends need matching female National Pipe Taper threads.

Which orientation must the valve be mounted in, and what common mistake should be avoided?

The valve must be installed horizontally; the frequent error is fitting it vertically or upside-down, which prevents the swing mechanism from operating correctly.

When should the internal brass seat and seal be inspected or replaced?

Check the brass seat and seal if flow drops below the rated 10 gpm, if leakage appears at the joint, or after prolonged exposure to temperatures near the 212 °F limit.
